Title: Additive Manufacturing of Molds for Fabrication of Insulated Concrete Block

Abstract

Oak Ridge National Laboratory (ORNL) worked with concrete block manufacturer, NRG Insulated Block, to demonstrate additive manufacturing of a multi-component block mold for its line of insulated blocks. Solid models of the mold parts were constructed from existing two-dimensional drawings, and the parts were fabricated on a Stratasys Fortus 900 using ULTEM™ 9085. Block mold parts were delivered to NRG and installed on one of their fabrication lines. While form and fit were acceptable, the blocks made from the molds collapsed when extruded from the printed molds during NRG’s testing. However, the project demonstrated significant time and cost reductions and achieving proper functionality through the use of different additive manufacturing techniques.
